Contraindications to Harvest of the Patellar Tendon Preexisting Patellofemoral Pain

Is preexisting patellofemoral pain a contraindication to harvesting the patellar tendon? The conventional wisdom is yes; it would not be a wise procedure in this situation. Rather, it is like hitting a sore thumb with a hammer! In the past, when chondromalacia was seen at the time of arthroscopy, the graft choice would be changed to hamstrings.

The Small Patellar Tendon

The harvesting of the central third of the patellar tendon in a small tendon is more theoretical than practical. The advice in a small patient with a tendon width of only 25 mm would be to take a narrower graft of 8 to 9 mm or use another graft source.

Preexisting Osgoode-Schlatters Disease

Shelbourne has reported that a bony ossicle from Osgoode-Schlatters disease is not a contraindication to harvest of the patellar tendon. Because the fragment usually lies within the bony tunnel, this bone may be incorporated into the tendon graft.
